Cleaner Pond Water With the Sea Side Aquatics C65M Pond Filter

Struggling with cloudy water and endless manual filter cleaning? The C65M does the hard work for you. It pairs mechanical and biological filtration in one automated unit, pulling debris out of your water and rinsing it away without you lifting a finger. Push your pond to 9,250 GPH of flow and let the self-cleaning drum keep everything clear while beneficial bacteria handle the rest.

  • Flow rate: Handles up to 9,250 GPH for reliable pond water turnover.
  • Two-stage filtration: Combines a rotating drum filter with a fluidized media bed for mechanical and biological treatment in one pass.
  • Fine debris removal: Patented woven 75/120 micron stainless steel mesh screens out particles down to 75 microns.
  • Self-cleaning: Automatic rinse function flushes waste through the 110 mm outlet, no hand scrubbing needed.
  • Biological capacity: 200 litre moving bed of helix media plus a 250 litre mat chamber for added surface area.
  • Oxygenation: Two 35 cm built-in air discs keep media active and water aerated.
  • Feed setup: Works with gravity, airlift, or pump feed, letting you match the filter to your pond layout.
  • Durable build: CNC-cut PP housing and drum with RVS 316/304 hardware and a UV resistant seal.
  • Smart control panel: Sensor-driven automatic cleaning with manual run/wash override and adjustable cleaning time and level.
  • Pump protection: Standard dry run protection helps guard your pond pump.
  • Easy servicing: Modular parts allow quick component swaps when maintenance is needed.

Combined Mechanical and Biological Filtration

Inside chambers of the Sea Side Aquatics C65M Drum Filter with spraybar valves, air disc and blue helix biological media

Two filtration stages work together inside a single housing, so you get physical debris removal and biological water treatment in one pass. With the lid removed, the internal layout is clear: the rotating drum filter sits on the left with its red-capped spraybar valves, a central pump chamber holds a black air disc, and the right-hand moving bed chamber is filled with blue helix media above the air discs.

  • Dirty water enters and hits the rotating drum filter (RDF) first, separating debris down to 75 microns.
  • Mechanically filtered water then flows through a fluidized bed of media powered by air, adding oxygen and driving biological breakdown.
  • The moving bed holds 200 litres of helix media, plus a separate mat chamber with 250 litre capacity for extra filtration surface.
  • Two built-in air discs of 35 cm keep the media in constant motion and the water oxygenated.

The result is water that stays clear and healthy for your fish, handled automatically day after day.


Automatic Self-Cleaning on the Sea Side Aquatics C65M RDF Filter

No more scrubbing screens by hand. When debris builds up, the unit rinses itself and flushes the waste out the drain.

  • The automatic rinse function flushes trapped debris away through the 110 mm waste outlet.
  • A removable spraybar blasts the mesh clean, and the removable waste water gutter makes maintenance simple.
  • The spraybar carries five red-and-white quick-release valve caps mounted along a stainless steel bar, sitting just in front of the mesh drum surface.
  • The drum wears a patented woven 75/120 micron stainless steel mesh for fine, durable filtration.
  • An installed 5 Bar cleaning pump supplies the rinse pressure.

Optional waste cleaning is available if you want to recover flush water rather than send it to drain.


Precision Build of the Sea Side Aquatics C65M Drum Filter

Every part is machined for a tight, lasting fit. The construction stands up to the demands of continuous pond duty.

  • Housing: PP 10/15 mm with a PP 15 mm drum, finished in a cream-coloured housing.
  • Precise CNC machine cut PP-construction for accuracy and strength.
  • Hardware in RVS 316/304 with a UV resistant seal.
  • Drum measures 60 cm x 50 cm in diameter, with a low 12 cm water running height.
  • Includes a 50 NM drive engine running at 4 RPM and comes with a lid.

Flexible Feed Options on the Sea Side Aquatics C65M Moving Bed Filter

Set the filter up to match your pond layout with three feed methods and adaptable plumbing. The closed housing carries multiple round inlet and outlet ports across the front and lower side walls, with the internal valve manifold visible along the open top edge.

  • Choose gravity, airlift, or pump feed to suit your installation.
  • The pump version has 30% less capacity, worth planning for when you size your system.
  • Standard inputs and outputs follow the drawing, and changes to inputs and outputs are possible.
  • Fitted with 2 x 90 mm drum-bypass connections.

Plug and Play Control on the Sea Side Aquatics C65M Combi + RDF Filters

Set it and forget it. The sensor-driven control panel manages cleaning cycles automatically, with full manual override when you want it. The panel carries a manual cleaning button, a red On/Off rotary switch, and a dedicated sensor connection, all marked with the Sea Side Aquatics seahorse logo and California address.

  • Automatic cleaning, plug and play with sensor detection.
  • Manual operation for run and wash on demand via the manual cleaning button.
  • Adjustable cleaning (turn/flushing) time and adjustable cleaning level.
  • 3 plugs give you control over the drum filter motor, cleaning pump, and pond pump, with each of the three power sockets clearly labelled for the motor drum filter, cleaning pump, and circulation pump.
  • Standard dry run protection guards the pond pump.
  • All components are built into quickly changeable modules for easy service.
